E类开关与PWM开关相比有很多优点。它们的低开关损耗允许在高频下高效运行。它们可以在低电磁干扰 (EMI) 下运行。此外，E类同步整流器还具有器件功耗低的优点。因此它在低功率电路中尤其有效。另一方面，稀疏方法可以通过在驱动电路中添加简单的逻辑电路来轻松调节输出电压。在本文中，我们建议将稀疏方法应用于 E 类同步整流器。实验电路是由基本E类逆变器和E类同步整流器组成的E类/sup 2/谐振dc/dc变换器。该电路可以通过控制（稀疏）同步整流器中MOSFET的驱动电压波形来调节输出电压。显示了一些实验结果，并与其他电路进行了比较。在低于 0.4 W 的低输出功率下，输出电压从 3.0 V 变化到 2.1 V 时，效率保持在 60% 以上。测得的最大效率为 78%。
Class E switches have many advantages in comparison with PWM switches. Their low switching losses allow for high-efficiency operation at high frequency. They can operate with low electro-magnetic interference (EMI). In addition, class E synchronous rectifier has the advantage of low power dissipation in the devices. So it is effective especially in low power circuits. On the other hand, thinned-out method can regulate the output voltage easily by adding a simple logic circuit to the drive circuit. In this paper, we propose to apply the thinned-out method to a class E synchronous rectifier. The experimental circuit is Class E/sup 2/ resonant dc/dc converter composed of a basic class E inverter and a class E synchronous rectifier. The circuit can regulate the output voltage by controlling (thinning-out) the drive voltage waveforms of the MOSFET in the synchronous rectifier. Some experimental results are shown, and compared with other circuits. At low output power less than 0.4 W, it was maintained over 60 percent for varying the output voltage from 3.0 V to 2.1 V. The maximum measured efficiency is 78 percent.
